Lincoln Electric KP2745-035A Copper Plus Contact Tip for Aluminum

The Lincoln Electric KP2745-035A is a premium contact tip designed specifically for the demands of aluminum MIG welding. Part of the Magnum® PRO expendables line, this contact tip features Lincoln's proprietary Copper Plus® technology. Unlike standard copper tips, the Copper Plus alloy is engineered to handle the higher thermal expansion and unique feeding characteristics of aluminum wire. The tip is rated for high-amperage applications up to 550A, making it suitable for heavy industrial fabrication.

One of the standout features of the KP2745-035A is its Anti-Seize™ thread design. In high-heat welding environments, contact tips can often fuse to the gas diffuser, making replacement difficult and potentially damaging the gun. The Anti-Seize threads feature a flattened profile that reduces the contact area within the threads, preventing thermal locking and ensuring quick, tool-free changes. This design significantly reduces downtime during consumable change-outs.

This product is supplied as a package of 10 contact tips. It is sized for .035-inch (0.9 mm) wire. While the product name references "Aluminum," please note that the tip itself is made from a high-grade copper alloy optimized for aluminum wire, ensuring superior conductivity and arc stability. It is compatible with Lincoln Magnum® PRO MIG guns and is an essential consumable for welders seeking consistent performance in aluminum applications.
